PAPER-ROLL HOLDER AND CUTTER.

' diminishing paper roll a.

Be it known that I, JOHN B. SEYMOUR, J r., a citizen of the UnitedStates, residing at the city of St. Louis, State of Missouri, haveinvented a certain new and useful Improvement in Paper-Roll Holders andCutters, of which the following is a full, clear, and exact description.

lvlyinvention relates to an improvement in that class of paper-rollholders and cutters in which the cutter adjusts itself by gravity to thediminishing paper roll, and has for its object to utilize the weight ofthe cutter-bar and.

the pressure produced thereon by cutting the paper for binding andholding the paper roll, and to leave a sufficient length of paperexposed at all times after being cut for seizing and unwinding the paperroll for afresh out.

It consists in the use of a specially-shaped cutter loar mounted overand adjustable by its gravity to the diminishing paper roll, the loweredge of the bar opposite to its cuttingedge bearing upon the paper roll,while the cutting-edge is on top and removed from the paper roll forcutting downward thereon instead of upward against, as heretofore.

On the accompanying drawings, Figure 1 represents a front elevation ofmy improved paper-roll holder and cutter; Figs. 2 and 3, a sideelevation and plan, respectively, thereof; Fig. 4, a plan of thecutter-bar detached, to an enlarged scale; and Fig. 5, an end view ofthe same, like letters of reference denoting like parts in all thefigures.

a represents the paper roll mounted on its spindle 1) between thestandards 0, in the usual manner. From the front of each standard 0projects a forwardly and upwardly inclined bracket cl, through whichfrom side to side is a longitudinal slot 6, the center line of which ispreferably coincident with the axle b of the paper roll a. Between theside brackets d, which, with their slots 6, are opposite to each other,is mounted transversely on the paper roll a the cutter-bar f, havingflattened ends g, with shoulders g, for sliding within the slots e asthe barf adjusts itself by gravity to the The cutter-bar f is speciallyshaped and arranged (seen more particularly in Figs. 4 and 5)-that is tosay, its lower edge f which is opposite to the cutting-edge f andpreferably convex transversely, bears upon the circumference of thepaper roll a, while the cuttingedge f ison top and removed from thepaper roll a, in lieu of being adjacent to the line of contact betweenthe latter and the cutter-bar. From the cutting-edge f the cutter-bar fextends at a suitable inclination backward and downward to a suitablewidth on top, and thence somewhat curved (or inclined) sharply downwardat the back to the lower convex edge f. Secured to the back of thecutter-bar f, but at a slight distancetherefroin, is a longitudinal rod'5, (see Figs. 4 and 5,) for supporting the paper after being cut, ashereinafter more particularly referred to. The paper being unwound fromthe roll a, is passed from the convex lower edge f of the cutter-bar f,between the back of the latter and the rod 1', and thence across the topof the bar f to the required length for cutting. In cutting the paperits free end overhanging the cutter (see Figs. 2, 3, 4, and 5) ispressed from above upon the cutting-edge f and the downward pressurethereby imparted to the cutter-bar f, plus its own weight, presses uponand holds the paper roll while being out. After being cut the free endof the paper, lying across the extended width of the top of thecutter-bar f, springs upward from the cutting-edge f and, beingprevented from falling back onto the paper roll a by the rod 2, therebyallows the paper to be seized for unwinding from the roll a previous toanother out. By curving the back of the cutter-bar f, as abovedescribed, the frictional resistance thereat to the passage of the paperfrom the roll a is reduced to a minimum.

I claim as my invention- 1. In a paper-roll holder and cutter, thecombination, with a suitable spindle or journaled support for the rollof paper, of a sliding cutter-bar or gravity-bar having a cuttingedge,said bar arranged with the plane of its blade in substantially a radialline drawn from the spindle and with its back resting on the roll toform a presser, and guides in which said bar slides to and from the rollor its spindle, substantially as and for the purposes described.

2. In a paper-roll holder and cutter, the

combination, with a suitable spindle or journaled support for the rollof paper, of a sliding knife-bar having a swell with concave faces toavoid friction of the paper, said bar arranged with the plane of itsblade in substantially a radial line drawn from the spindle and with itsback resting on the roll to form a presser, and guides in which said barslides to and from the roll or its spindle, substantial] y as and forthe purposes described.

3. In a paper-roll holder and cutter, the combination, with a suitablespindle or journaled support for the roll of paper, of a slidingknife-bar ha ing a swell with concave faces to avoid friction, and aconfining-rod for the paper, said bar arranged with the plane of itsblade in substantially a radial line drawn from the spindle and with itsback resting on the roll to form a presser, and guides in which said barslides to and from the roll or its spindle, substantially as and for thepurposes described.

4. In a paper-roll holder and cutter, the combination, with a suitablespindle or journaled support for the roll of paper, of a slidin gcutter-bar or gravity-bar having a cuttingedg'e, said bar arranged withthe plane of its blade in substantially a radial line drawn from thespindle and with its back resting on the roll to form a presser, andguides in which said bar slides to and from the roll or its spindle,said bar having shoulders to prevent endplay of knife in its guide,substantially as and for the purposes described.

I11 testimony whereof I have affixed my signature, in presence of twowitnesses, this 19th day of October, 1888.
